Dev-Team – Losing GPS Functionality When Unlocking 06.15.00 Baseband

The Dev-Team has added another update to their blog post about the ultrasn0w unlock for iOS 4.2.1. The update talks about an issue with retaining GPS when unlocking iPhones with 06.15.00 baseband. It seems that some people on 06.15.00 are losing their GPS functionality when they unlock their device. The Dev-Team does not currently have a fix for this problem and says that, even though the problem does not occur for everyone, you should just assume you will lose GPS capabilities when ulocking 06.15.00. However, they are working on a fix for the problem. Check out the full details below.

Update #5: Unlockers have been reporting mixed results about GPS functionality at 06.15.00. Until we can track down what differentiates those who retain GPS vs. those who lose it, be conservative and assume you’ll lose GPS at 06.15.00. As we work on finding the cause (and possibly a fix), please report your personal findings in our comments section. (Update: early indications are that while 06.15.00 is capable of GPS, it will require some further hacks. But please still be conservative and assume you will lose GPS at 06.15, in case the hacks don’t work).

thanks for the new unlock,i live in spain and all ten of my iphones have no gps.infact i dont know of any one that does have after this unlock 06.15.00,hope you fix it soon,think beter to to send out an unlock that it would be impossible to ever upgrade with itunes again,,,we all should have stayed with 3.1.3 ,,,,regards simon

I first Update via iTunes 4.2.1, then JB, And CHECK 100% sure my GPS works 10/10, just for that reason I JB + Update BB 06.15 for unlock, and inmediatly CHECK GPS and was dead. Now Downdrade 4.1, check GPS and doesn’t work, and is not a surprise because keep the same BB 06.15. Please Quick Fix for this, I use a LOT my GPS.

Hello Dev-Team, I updated my baseband to 6.15.00 and unlocked with ultrasnow few days ago. I observe that the GPS is not totally lost as we update to this baseband, It seems that the GPS signal just becomes weaker. It can locate my current position but its not that accurate compare to the previous one.

I had much of the same, GPS still works but doesn’t seem to correlate location to city streets so that the circular error causes my location to jump wildly rather than realize what road I’m driving on.
